I Referring more particularly to the drawings; is a table which.ismounted on a shaft 2 having a step bearing 3. The shaft 2 also'"has abearing 4. in a supporting cast? mg or bracket 5. Mounted on the shaft 2intermediate the hub of the table 1 and the bearing 'is a spider 6 whichis connected to the under face'of the table 1 by means of bolts '7, sothat the two rotate together. Powerfor armin the spider 6' is obtainedfrom the shaft 7 which is driivenby a belt wheel -7",' oranyfothersuitable means. On the inner end of the shaft 7 is a gear 8which meshes With agear9 which is carried by a shaftl'O. ShaftjlO isprovided with four bearings, one in the-block 11, one in the casting, 12and two others in the blocksld --.and 14, respectively; Mounted atone.side of the block 13 is.a bevel gear' l5 which meshes withta gear 16 ona shaft 17. Shaft 17 is vertical and is carried in two bearingssupported by the casting 12. At the upper end of the shaftli'fisthemember 18 which gives to the spider 6 and the table 'la peculiar step bystep movement. One end of the member, 18 is. i i-"the form of Hank whichcarries an upwardly projecting pin 19, on which is mounte d'a revolubespool. orroller 20. Theotherfpart of tlieinember18 isiin the form ofajsemi-circular disk or cam 21' which lies in a' lower plane than: theroller 20, as clearlyshown in Fig. 11.

The exterior edge of the spider fi is provided with two sets ofsurfaces, one for coeperat IIIg'WIth the roller 20 and the other forcooperating with the disk 21. The surfaces which cooperate with theroller 20 are in the form ofiteeth 22 which lietin the same plane astheroller 20 andare separated by recesses slightly widerthan thediameter of the roller On a lower plane than the teeth 22 and- 20. onthe samelevel with the disk 21', theedge of the spider 6' is providedwith a series of I earn surfaces, 23 shown in plan partly in dottedlines in Fig. 12. Thesecam surfaces are arcs ofkcircles whose radiicorrespon to the radius of the exterior edge of the disk 21, the pointsof intersection between the surfaces 23 being intermediate the teeth 22.Now it will be understood that the shaft 17 is rotated continuously bythe connections previously described with the shaft 7, but

' that while tlie'diskl21 remains in engage spider 6 and consequentlythe table lis held ment with a particular. cam surface 23, the

firmly in stationary position. Hdwever, as thedisk21 passesout ofengagement with -its cooperating, cam surface the roller engages one oftheteeth 22 giving the spider 1 and table a positive movement i'n thedirection ofthe arrow.

The table 1 is provided with a shoulder 24 which causes the exteriorsurface of. the

table to act asla shelf upon which may be placed tins 25 to'be used forbaking. cup

cakes. Intermediate two adjacent tins are provided upstanding ridges ,orwebs 26 which are each provided with a lug 27 for holding'the tinssecurely to the table while the machine is in operation.

' Carried by a standard such as 28 is astationary cover plate or apron29 which covers "a little more than half of the surface of therevolving'tins, and upon which is mounted the cutting and feedingmechanism herein- 'At the outer end ofthe shaft 10 is a gear wheel 30which meshes with a gear "31 on the shaft 32. At the end of the shaft 32opposite from the gear 31 is a crank arm 33 which is provided with aslot 34 which provides an adjustable connection with the-link or rod 35.The rod 35 is connected at.its

upper end to, a lever 36 which is loosely mounted on the shaft 37. Sincethe member- 33 rotates continuously the upper end of the rod 35 andconsequently the lever arm 36 is oscillated about the. center of shaft.37. The lever .ttiIIl 36 carries 3 a pawl 38 shown. in

dotted lines in Fig.2 which engages with the teeth of a ratchet"='wheel39. Conse ,;quently" as the} lever 36 oscillates it gives a step by stepmovement, to the shaft 37 by ,lnieans of thepawl' and ratchet. Mouiite'don.

the shaft 37 are two drums or wheels 40 and'4l for-"driv ng: the paperwebs. 42 and 4'3 from which the pieces are eut'whi'ch are placed in'the'tins. Mountd immediately 7 below the drums'40,and"41 respectiyely-iaredrums 44 and 45, the web 3142 'b'eing; led,

around the outer surface of ,the'druing40. and

' in between'drums 40' and 44 wliileth "web 43'islled aroundthe outersurface" of the drum 41 and in between the "drumsj41 and 45. Theuper'part of th'e drum 41 being below the evel of the'table the web 43is guided. on to the drum 41 by means of the roller 46. It will beunderstood moreover that the drums 44 and 45 are suspended below drums40 and 41 by meansof'brackets 47-47. The shaft" .37 being positivelydriven, the drums 40 and 41' inconnection with 44 and'45 serige to feedthe paper webs positively. The webs 42 and 43 are carried by separaterollers 4848 which are mounted on a shaft 49, carried in brackets 5050mounted on the upper face of the plate 29. The webs 42 and 43-are alsoguided by the rolls 5151'. In order to prevent the webs 42 and 43 fromfeeding too freely I provide friction rollers'52-52 which are carried bya shaft 53 which is pivotally mounted in the brackets 50 50., If desiredthe shaft 53 may be thrown up into'the dotted. position shown in Fig. 2so as to permit the ready removal orreplacement of the webs 4243.

The brackets 50 are-provided with extensions 5454 against Which the arms55-55 which support the shaft 53 may. rest when the rolls 52-are lifted.After leaving rollers i 51 the webs 42 and 43 run hO-rizontallyuntilthey reach the drum 40 and the roll .46 respectively. In passing throughthis horizontal stretch the webs. are cut to provide pieces for liningthe tins and the cut pieces are placed automatically in the tins,Asshown in Figs. 1 and 2 the tins have a radial depth of three cups orrecessesf Consequently I provide three cutters 56, 57 and 58. I'Owingthat of the top of the tins; Consequently.

the outer edges of t he cutters overlap the to the fact that the piecesof paper are cut outer edges of the recesses in the tins and. I

.all three-of the putters can not-be placed in a row radially of thetab'leybut one is oflset from the other two, as plainlyshown in Fig.

1. The detailflof the? cutter mechanism is shown in Figs 7, 8 and 9, thecutter 57 being selected for detailed illustration. Each cuttingmechanism comprises a stationary and a reciprocating part, thestationary part be ing carried on the upper face of the plate 29 andcomprising anupstanding cylindrical knife plate 59 which has a sharpcircular knife edge at its phe ixed knife 59 iheld in position byannular plates 60, plates -60 being attached to the face oftheplate 29by screws 61, and each extending approximately 90 degrees are. Plates 60form a central aperture. through which the pieces of "paper 62 shownFig. 7 maybe placed in [the tins after being cut from the. web. At-

tached to theinner face of the knife 59 and ,held between two adjoiningplates 60 areffour radial knives 63 placed 90 degrees apart around theplate 59, 'and extendingto the edge -of the aperture '64 in the plate29.

Above the knife 59 is a reciprocating knife 5 which is also cylindricalin form but has its cutting edge at the bottom, the knife" 65 matingwith the knife 59on the inside. -The" knife 65 also carries radiallyplaced knives 66, which are mounted between ridges 67-67 on the interiorface of the part 68, and are also held in place by two, sets of screwsas shown in Fig. 7. The radial knives 66 cotins the edges of the slitsmay overlap each other and allow the papersto be forced into the tinswithout wrinkling. One of the papers 62 having the slits cut therein isshown in Fig. 13. l

The part 68 is mounted at the end of a tubular sleeve 69 which slides ina bearing movement between the two.

in the bracket 70. and is operated by being attached to a yoke plate 1.-Mounted to slidewvithin the sleeve 69 is a rod 7 2 'at the lower end ofwhich is mounted the mecha nism for placing the papers 62 in the tinyafter the papers have been cut from the web. This mechanism consists ofa stamping member or head 73 which is attached to a stud or shank 74.The end ofthe rod 72 is drilled out to receive the shank 74 and the rod72 is also slotted as at 7 4 to receive a pin 75 for retaining the shankwithin'the end of the rod and for allowing 'a certain relative The shank74 does not fit closely in its bore, so that head '73 is allowed play inboth the vertical and horizontal directions. A spring 76 normally forcesthe head 73 outwardly so that the-pin lleS at the lower .end of theslot, but when the head comes in contact with the interior of the tinsthe spring 76 may be compressed,

thus avoiding pounding on the tins, but insuring that the paper shall befirmly placed in position.

The cutting mechanism and the stamping mechanism justdescribed areoperated from two .cam grooves formed in opposite faces of the cam plate77 which is mounted on the shaftlO between the blocks'13and 14. Camrollers mounted in these grooves operate rods 78 and 79 respectively.One of these rollers 86 is shown in dotted lines in Fig. 3,

being hidden by the gear 30 and the member 87. These rollers are mountedon the plates 87 and 88, the supporting nuts being shown in Fig. 2. Itwill be understood that the plates 87 and 88 are forkedand embrace theshaft 10 on each side, so as to avoid the necessity of a fixedbearing'and an additional link at the upper end of the rods 78 and 79.The rod 78 connects at its upper end with a pivoted lever 80, as bestshown in Fig. 3. This lever 80 is pivoted to a casting 81 which ismounted on top of' a bridge shaped casting'82 in which are the bearingsfor the tubes 69 and rods 72 previously mentioned. At the end of thelever opposite the operating rod 78, the lever con- 'nects with theshaft 89 which is pivoted in i lever' in turn with the pivoted shaft 89,also pivoted in the castings '81 and 81% The shaft 89" carries, a lever83 which is connected at its outer end to a short link 84 pivoted inturn with the-plate 85,, to which are connected the rods72 for operatingthe heads 73. 7 It will be understood that the grooves in the cam plate77 are so cut that. the rod 78' will first be operated to cut one ofthe. pieces 62 from the webs and that the rod 79 will next be operatedto force the piece down into the tin. Owing to the [fact/that thecuttingmechanism 56 is in a different radial plane from cutters 57 and58, it follows that in order to "avoid an unnecessary waste of paper thecutter 56 is provided with a separate web of paper from the cutters 57and 58. This arrangement has been previously described, but it followsfrom this that the web 43 which cotiperates with the'single cutter 56should be fed only half as fast as the web 42 which serves the cutters57 and 58. This difference in speed of travel between the two websisprovided' for by tlie different d-iam-. eters of the driving indrums-40 and 41.

Carried on the plate 29, in a different radial position from the cuttingand stamping mechanism, is a feeding mechanism for. placing a-properamount of dough in each tin. This mechanism comprises a hopper 90 whichappears in Figs. 1. 2 and 3, and is shown in detail'in Fig. 4. Atthebottom :of the hopper are mounted three sets of feeding. mechanism whichare mounted below a plate or member 91 having apertures therein, throughwhich the dough feeds, these apertures being separated by ridges 91. Thehopper 90 is bolted directly to plate 91 by whi ch it is supported.Immediately below the member 91 is a revoluble member 92 which is formedwith gear teeth 93 on its outer surface. Each of the members 92 providedwith a central aperture, to the inner surface of which is attached afeeding worm or screw '93 so that the worm. turns with the member 92.The members 92 are mounted to revolve in bearings 94 supported tubes97-97, into which the worms 93. de-

pend. Below the mouths of the tubes 97 is mounted cut-off mechanismespeciall illus trat'ed in Figs. 5 and6. This cutoff mecha- 95. Theplate 98 'is provided with elongated apertures 10110l, through whieh thedough delivered by the worms 93 may drop into the tins Qn the under faceof the plate 98 are cutting plates 102-102, which are- 5 ,slott'edasshown at 103, so that they may be adjusted on the plate 98 to vary thesize of the aperturelOl, and consequently the point at which. they cutoff the dough from a given tin, thus regulating the amount ofdough in 29the tins. Plates 102 are provided with crescent shaped cutting edges104-104, a shown in Fig. 6. q I The; feeding'lnechanismv is operated'from the shaft 7 'by the gear wheel 105 which meshes With'a. gear 106\vhich'drives a shaft the table 1 and an empty tin inserted in its placewithout the .necessity for stopping the machine.

It will be understood by those skilled in mechanical arts that whileIhave shown and described'the preferred form of my device,

that various rearrangements. and modifications thereof may be madewithout departing from the splrit .of my invention. For instance insteadof a circular revolving table I may use an endless belt or'conveyer forcarrying the tins, and mount the cutting, stampinggand feeding mechanismabove such conveyer instead of above the table shown. Consequently itwill be understood that I contemplate all modificatio slandrearrangements which are mechanicifll the device shown and describedherein.

Having thus described my invention, what Iclaimisf:"- g,

1. The combination of a movable device for carrying baking tins,-mechanism-for lining s'aid tins with paper, means for placing dough onsaid paper, and meansfor moving said device. v

107 at the upper endof which is a gear 108. 2. The combination of amovable device :Ihe teeth of, the gear 108 mesh with the, teeth 93 onthe outer surface of one of the members 92, and as the teeth 93 of allthe "Ine'mber 92' mesh with each other, the gear 108 drives them all inunison. The plate 98, however, is operated from the cam 109, alsocarried on the shaft 7, and shown in detail in Fig. 10. The cam 109drives a lever 110 a v which operatesa rod 111. Rod-.111 connects at itsupper end to a lever 112,,whichconnects with a shaft'120 pivoted at theupper end to castings 113 Shaft 120 carries two lever arms 112 which areconnected by short 49f links 113, to the plate 98 in order to recipro.cate' the plate.

' In the operation of understood that the table 1 carrying the-cake tins25, is given a step by step movement by .n means of the mechanismheretofore described in which there is a perceptible pause between eachforward movement or step of thertable. While the table 1 isstationary.between the sucees'sive steps, the "cutting 50 mechanism cuts thepieces 62 from the webs 42 and, 43, and thestamping me'chanism "placesthe pieces of paper in the tins As the table is stepped around tinscontaining papers are brought under. the dough feeding mechanismwhereupon during one .of .the stationaryrperiods the plate 98 isoperated by the link motion connected thereto to present apertures 101beneath the tubes. 97 whereupon the worms 93 deliver a charge or doughinto the tins. Upon the return stroke .Qo-f the'plate 98 the dough iscut off and immediatelv thereafter the table is moved forward a step andthe operation just described is repeated.
